Subject [jira] Closed: (DIRSERVER-681) Memory leak in ADS ?
Date Thu, 27 Jul 2006 21:45:20 GMT
     [ http://issues.apache.org/jira/browse/DIRSERVER-681?page=all ]

Emmanuel Lecharny closed DIRSERVER-681.
---------------------------------------

    Resolution: Fixed

Seems to be a false alarm. The memory should be carrefully set when using huge caches.

> When doing thousands of searches, at a point, the memory get exhausted, and the server
stop to deliver responses.
> The first bet is that we have a memory leak somwhere. Using yourkit shows that the heap
increase continuously while search requests are being processed.
> However, I have done an extensive test whith all cache set to 1, and launched an heavy
test (100 000 random search requests over a 10 000 entries base), with a Heap size set to
25 M, and everything is running fast (even if it's slow).
> So the second bet would be that cache setting is to big in regard to the allocated memory,
and we just exhaust memory using too much cache.
> I will try to do a 12H test with 1 sized cache tonite, and a 48H test with 100 sized
cache on tuesday and wenesday, to check which hypothese is the good one (hope the second will
be it :).
